Definitions
- the present invention relates to a cooking appliance and, more particularly, to a pressure cooking appliance.
- Pressure cookers are known from the prior art. Such devices are used in the professional sector, in particular in large kitchens, such as canteens, and the increased pressure during cooking can significantly shorten the cooking time.
- Such Druckgarieri as for example from the EP 2 908 705 B1 are known, have a crucible which has a rectangular cooking space which can be closed by a pivotable lid, the crucible being pivotably mounted in a cooking device frame by means of a crucible pivot axis and the lid being pivotable about a lid pivot axis by means of a drive, the cooking device frame having two has lateral frame sections and a connecting frame section which is arranged on the rear side of the crucible and connects the two lateral frame sections.
- the lid In the pressure cooker of the applicant, which has been known in the market under the name "Flexi chefs" for many years, the lid is mounted on both sides of the lid in the two side frame sections via its lid pivot axis.
- the two side frame sections are of unequal width wider lateral frame section, the drive of the lid and other elements of the cooking device, such as a display and operating device, a cooking device control and supply devices for water, etc. are housed.
- the present invention is therefore based on the object of avoiding the above-mentioned disadvantages and of proposing a crucible cooking appliance, in particular a crucible pressure cooking appliance, in which a favorable introduction of force for pivoting the lid is created.
- this object is achieved in that two pivot shaft sections are arranged around the cover pivot axis, which are rotatably arranged on the connection frame section, and that the drive for pivoting the cover is arranged in the connection frame section.
- each of the pivot shaft sections is arranged in an area which essentially corresponds to the center of the distance from a center axis of the cover to the corresponding left or right side edge of the cover. This results in a particularly favorable mounting of the cover, in particular to reduce the risk of deformation at high pressure.
- the drive for pivoting the cover in the direction of the center of the cover is arranged on one of the pivot shaft sections and acts on this.
- the torque applied by the drive to pivot the lid is thus introduced at a relatively small distance from the central axis of the lid, which enables a lighter construction of the lid pivot drive because the torque transmitted is lower than in the solution According to the state of the art.
- the drive for pivoting the cover comprises a linear drive which is able and configured to pivot a pivot lever mounted about a pivot axis, which engages with a sleeve that extends around one of the pivot shaft sections and is rotatably connected to it.
- a linear drive which is able and configured to pivot a pivot lever mounted about a pivot axis, which engages with a sleeve that extends around one of the pivot shaft sections and is rotatably connected to it.
- a particular advantage results from the fact that the pivot lever has external teeth which mesh with external teeth of the sleeve. This creates a simple design of the power transmission from the drive of the cover to the cover, with the possibility of using standard elements such as gear wheels.
- the force of the drive for pivoting the cover up takes place in the lifting mode or in the extension mode of the linear drive, because the drive can be loaded more heavily in the pushing direction, i.e. when extending, than in the pulling direction, i.e. when retracting.
- the present invention advantageously proposes that the external toothing of the pivot lever and / or the external toothing of the sleeve extend only over a partial circumference of the pivot lever or the sleeve. This results in advantages through space savings, cost savings and more flexible design options.
- the drive for pivoting the lid of the cooking appliance can be driven electrically, hydraulically or pneumatically.
- a hydraulic drive it is possible to close the cover by releasing the hydraulic pressure in a controlled manner, which is promoted by the relatively high weight of the cover.
- the sleeve has an inwardly protruding feather key, which engages in a corresponding keyway in the associated pivot shaft section. This creates a structurally simple and effective power transmission.
- feather key and the sleeve are formed integrally with one another and thus components and assembly time can be saved.
- the sleeve which is connected non-rotatably to the associated swivel shaft section, is formed from a plurality of sleeve rings which have the external toothing. This leads to a simple construction of the sleeve, with the external toothing and in particular the external toothing section occupying only part of the outer circumference being able to be produced in a favorable manner, for example by means of laser cutting.
- pivot lever has a number of lever rings with external teeth corresponding to the number of sleeve rings.
- the sleeve rings and / or the lever rings are advantageously connected to one another, in particular pinned, welded or screwed.
- the number of rings can advantageously be adapted as a function of the weight of the cover, the design and size of the sleeve rings or lever rings and / or their material.
- a cooking device 1 is shown in plan view in the embodiment as a pressure cooking device.
- the pressure cooking appliance 1 has a rectangular crucible 3, as is known in the prior art, and this crucible 3 is pivotably mounted on a crucible pivot axis 4.
- the crucible pivot axis 4 is in turn mounted in a cooking device frame 7, the cooking device frame 7 being arranged in a manner known per se a left side frame section 9, a right side frame section 11 and a rear or on the back of the crucible connecting the left and right side frame sections Has connecting frame section 13.
- the left side frame section 9 is made relatively slim, whereas the right side frame section 11 is made significantly wider. It includes, inter alia, a display and operating unit 27 with a touchscreen 29 and other elements such as a device control (not shown), a water supply (not shown) and electrical connecting cables (not shown).
- the wide frame section can be arranged to the left or right of the crucible. If operation on the left side is required, the left frame section is accordingly wider and the right one is narrower. There are also so-called team devices with several cooking chambers. It is also possible to design both frame sections with the same width.
- Fig. 1 It can also be seen that the crucible 3, in which a rectangular cooking space 25 is formed, is covered by a lid 5.
- Numeral 23 denotes a central axis of the cover 5, which is located between a left side edge 35 and a right side edge 37 extends centrally.

Description
Die vorliegende Erfindung betrifft ein Gargerät und insbesondere ein Druckgargerät. Druckgargeräte sind aus dem Stand der Technik bekannt. Derartige Geräte kommen im professionellen Bereich, insbesondere in der Großküche, wie einer Kantine zum Einsatz, wobei durch den erhöhten Druck während des Garens die Garzeit signifikant verkürzt werden kann.The present invention relates to a cooking appliance and, more particularly, to a pressure cooking appliance. Pressure cookers are known from the prior art. Such devices are used in the professional sector, in particular in large kitchens, such as canteens, and the increased pressure during cooking can significantly shorten the cooking time.
Derartige Druckgargeräte, wie sie beispielsweise aus der
Bei dem Druckgargerät der Anmelderin, welches unter dem Namen "FlexiChef' seit vielen Jahren im Markt bekannt ist, ist der Deckel über seine Deckelschwenkachse zu beiden Seiten des Deckels in den beiden seitlichen Gestellsabschnitten gelagert. Die beiden seitlichen Gestellsabschnitte sind ungleich breit, wobei in dem breiteren seitlichen Gestellsabschnitt der Antrieb des Deckels und weitere Elemente des Gargerätes, wie beispielsweise eine Anzeige- und Bedieneinrichtung, eine Gargerätesteuerung und Zuführeinrichtungen von Wasser, etc. untergebracht sind.In the pressure cooker of the applicant, which has been known in the market under the name "FlexiChef" for many years, the lid is mounted on both sides of the lid in the two side frame sections via its lid pivot axis. The two side frame sections are of unequal width wider lateral frame section, the drive of the lid and other elements of the cooking device, such as a display and operating device, a cooking device control and supply devices for water, etc. are housed.
Durch den während des Druckgarens erzeugten starken Überdruck von bis zu 1,0 bar über dem Normaldruck ist eine besonders dichte Verschließposition des Deckels auf dem Tiegel notwendig. Dadurch bedingt weist der Deckel eine versteifte Konstruktion auf, die ein erhebliches Gewicht des Deckels mit sich bringt. Dies führt zu einer ungünstigen Krafteinleitung von deutlich außerhalb des Tiegels, wobei zusätzlich die Gefahr der Verformung des Deckels bei großem Druck besteht. Diese Anordnung bedingt weiterhin eine massive Konstruktion des Antriebs und der Kraftübertragung auf die Drehachse des Deckels, was mit einem großen Platzbedarf einhergeht. Zudem müssen die seitlichen Gestellsabschnitte deutlich höher sein als die Oberseite des Tiegels, weil sie die Drehachse des Tiegels lagern.Due to the strong overpressure of up to 1.0 bar above normal pressure generated during pressure cooking, a particularly tight closing position of the lid on the pan is necessary. As a result, the cover has a stiffened construction, which brings with it a considerable weight of the cover. This leads to an unfavorable introduction of force from well outside the crucible, with the additional risk of deformation of the lid under high pressure. This arrangement furthermore requires a massive construction of the drive and the power transmission to the axis of rotation of the cover, which is associated with a large space requirement. In addition, the side frame sections must be significantly higher than the top of the crucible because they support the axis of rotation of the crucible.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, die oben genannten Nachteile zu vermeiden und ein Tiegel-Gargerät, insbesondere ein Tiegel-Druckgargerät vorzuschlagen, bei dem eine günstige Krafteinleitung zum Verschwenken des Deckels geschaffen wird.The present invention is therefore based on the object of avoiding the above-mentioned disadvantages and of proposing a crucible cooking appliance, in particular a crucible pressure cooking appliance, in which a favorable introduction of force for pivoting the lid is created.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass um die Deckelschwenkachse zwei Schwenkwellenabschnitte angeordnet sind, die drehbeweglich an dem Verbindungsgestellabschnitt angeordnet sind, und dass der Antrieb zum Schwenken des Deckels in dem Verbindungsgestellabschnitt angeordnet ist.According to the invention, this object is achieved in that two pivot shaft sections are arranged around the cover pivot axis, which are rotatably arranged on the connection frame section, and that the drive for pivoting the cover is arranged in the connection frame section.
Durch die Lagerung des Deckels in dem Verbindungsgestellabschnitt wird die Gefahr der Verformung des Deckels im Druckgarbetrieb erheblich reduziert. Da die Krafteinleitung des Antriebs zum Schwenken des Deckels in dem Verbindungsgestellabschnitt erfolgt, wird eine günstigere Drehmomentübertragung ermöglicht. Durch die Lagerung des Deckels im Verbindungsgestellabschnitt ist es möglich den Deckel leichter und flacher zu gestalten und so Gewicht und Material zu sparen.By mounting the cover in the connecting frame section, the risk of deformation of the cover during pressure cooking is considerably reduced. Since the force of the drive for pivoting the cover is introduced into the connecting frame section, a more favorable torque transmission is made possible. By mounting the cover in the connecting frame section, it is possible to make the cover lighter and flatter and thus to save weight and material.
Vorteilhafterweise ist jeder der Schwenkwellenabschnitte in einem Bereich angeordnet, der im Wesentlichen der Mitte des Abstands von einer Mittenachse des Deckels zum entsprechenden linken bzw. rechten Seitenrand des Deckels entspricht. Dadurch ergibt sich eine besonders günstige Lagerung des Deckels, insbesondere zur Verringerung der Verformungsgefahr bei hohem Druck.Advantageously, each of the pivot shaft sections is arranged in an area which essentially corresponds to the center of the distance from a center axis of the cover to the corresponding left or right side edge of the cover. This results in a particularly favorable mounting of the cover, in particular to reduce the risk of deformation at high pressure.
Weiterhin ist vorteilhaft, dass der Antrieb zum Schwenken des Deckels in in Richtung Deckelmitte an einem der Schwenkwellenabschnitte angeordnet ist und an diesem angreift. Das von dem Antrieb aufgebrachte Drehmoment zum schwenken des Deckels wird somit in einem relativ geringen Abstand von der Mittelachse des Deckels eingeleitet, wodurch eine leichtere Konstruktion des Deckelschwenkantriebs ermöglicht wird, weil das übertragende Drehmoment geringer ist als bei der Lösung nachdem Stand der Technik.It is also advantageous that the drive for pivoting the cover in the direction of the center of the cover is arranged on one of the pivot shaft sections and acts on this. The torque applied by the drive to pivot the lid is thus introduced at a relatively small distance from the central axis of the lid, which enables a lighter construction of the lid pivot drive because the torque transmitted is lower than in the solution According to the state of the art.
Vorteilhafterweise umfasst der Antrieb zum schwenken des Deckels einen Linearantrieb, der in der Lage und dazu eingerichtet ist, einen um eine Drehachse gelagerten Schwenkhebel zu Verschwenken, der in Eingriff steht mit einer Hülse, die sich um einen der Schwenkwellenabschnitte erstreckt und mit diesem drehverbunden ist. Dadurch wird eine platzsparende Konstruktion des Deckelschwenkantriebs geschaffen, sodass der rückwärtige Verbindungsgestellabschnitt entsprechend schlank ausgebildet sein kann.Advantageously, the drive for pivoting the cover comprises a linear drive which is able and configured to pivot a pivot lever mounted about a pivot axis, which engages with a sleeve that extends around one of the pivot shaft sections and is rotatably connected to it. This creates a space-saving construction of the cover pivot drive, so that the rear connecting frame section can be designed to be correspondingly slim.
Ein besonderer Vorteil ergibt sich dadurch, dass der Schwenkhebel eine Außenverzahnung aufweist, die mit einer Außenverzahnung der Hülse in Eingriff steht. Dadurch wird eine einfache Ausgestaltung der Kraftübertragung des Antriebs des Deckels auf den Deckel geschaffen, wobei hier die Möglichkeit des Einsatzes von Standardelementen, wie Zahnrädern, besteht. Insbesondere ergibt sich der Vorteil, dass die Krafteinleitung des Antriebs zum Hochschwenken des Deckels im Hubbetrieb bzw. Ausfahrbetrieb des Linearantriebs erfolgt, weil der Antrieb in Druckrichtung, also beim Ausfahren stärker belastbar ist als in Zugrichtung, also beim Einfahren.A particular advantage results from the fact that the pivot lever has external teeth which mesh with external teeth of the sleeve. This creates a simple design of the power transmission from the drive of the cover to the cover, with the possibility of using standard elements such as gear wheels. In particular, there is the advantage that the force of the drive for pivoting the cover up takes place in the lifting mode or in the extension mode of the linear drive, because the drive can be loaded more heavily in the pushing direction, i.e. when extending, than in the pulling direction, i.e. when retracting.
Vorteilhafterweise schlägt die vorliegende Erfindung vor, dass die Außenverzahnung des Schwenkhebels und/oder die Außenverzahnung der Hülse sich nur über einen Teilumfang des Schwenkhebels bzw. der Hülse erstrecken. Hierbei ergeben sich Vorteile durch Platzersparnis, Kostenersparnis und flexiblere Gestaltungsmöglichkeiten.The present invention advantageously proposes that the external toothing of the pivot lever and / or the external toothing of the sleeve extend only over a partial circumference of the pivot lever or the sleeve. This results in advantages through space savings, cost savings and more flexible design options.
Im Rahmen der vorliegenden Erfindung kann der Antrieb zum Verschwenken des Deckels des Gargerätes elektrisch, hydraulisch oder pneumatisch angetrieben sein. Bei einem hydraulischen Antrieb besteht die Möglichkeit, dass Schließen des Deckels durch kontrolliertes Ablassen des Hydraulikdrucks zu bewerkstelligen, was durch das relativ hohe Gewicht des Deckels gefördert wird.In the context of the present invention, the drive for pivoting the lid of the cooking appliance can be driven electrically, hydraulically or pneumatically. In the case of a hydraulic drive, it is possible to close the cover by releasing the hydraulic pressure in a controlled manner, which is promoted by the relatively high weight of the cover.
Weiterhin ist vorteilhaft, dass zur Drehverbindung der Hülse mit dem zugeordneten Schwenkwellenabschnitt, die Hülse eine nach innen vorspringende Passfeder aufweist, die in eine entsprechende Passfedernut in dem zugehörigen Schwenkwellenabschnitt eingreift. Dadurch wird eine konstruktiv einfache und wirksame Kraftübertragung schaffen.It is also advantageous that for the rotary connection of the sleeve with the associated pivot shaft section, the sleeve has an inwardly protruding feather key, which engages in a corresponding keyway in the associated pivot shaft section. This creates a structurally simple and effective power transmission.
Besonders vorteilhaft ist dabei, wenn die Passfeder und die Hülse einstückig miteinander ausgebildet sind und so Bauteile und Montagezeit gespart werden können.It is particularly advantageous if the feather key and the sleeve are formed integrally with one another and thus components and assembly time can be saved.
Ein großer Vorteil ergibt sich weiterhin dadurch, dass die mit dem zugehörigen Schwenkwellenabschnitt drehfest verbundene Hülse aus einer Mehrzahl von Hülsenringen ausgebildet ist, die die Außenverzahnung aufweisen. Dies führt zu einem einfachen Aufbau der Hülse, wobei die Außenverzahnung und insbesondere der nur einen Teil des Außenumfangs besetzende Außenverzahnungsabschnitt günstig, beispielsweise mittels Laserschneiden erzeugt werden kann.Another great advantage is that the sleeve, which is connected non-rotatably to the associated swivel shaft section, is formed from a plurality of sleeve rings which have the external toothing. This leads to a simple construction of the sleeve, with the external toothing and in particular the external toothing section occupying only part of the outer circumference being able to be produced in a favorable manner, for example by means of laser cutting.
Diese Vorteile werden auch dadurch erreicht, dass der Schwenkhebel eine der Anzahl der Hülsenringe entsprechende Anzahl an Hebelringen mit Außenverzahnung aufweist.These advantages are also achieved in that the pivot lever has a number of lever rings with external teeth corresponding to the number of sleeve rings.
Vorteilhafterweise sind die Hülsenringe und/oder die Hebelringe miteinander verbunden, insbesondere verstiftet, verschweißt oder verschraubt. Dabei kann Vorteilhafterweise die Anzahl der Ringe in Abhängigkeit von dem Gewicht des Deckels, der Bauform und Baugröße der Hülsenringe bzw. Hebelringe und/oder deren Material angepasst werden.The sleeve rings and / or the lever rings are advantageously connected to one another, in particular pinned, welded or screwed. The number of rings can advantageously be adapted as a function of the weight of the cover, the design and size of the sleeve rings or lever rings and / or their material.

Sowohl die Hülsenringe 59 als auch die Hebelringe 61, Letztere zusammen mit dem Schwenkhebellagerelement 71, sind miteinander verstiftet, verschweißt oder verschraubt und bilden sozusagen ein "Schwenkhebelpaket" bzw. ein "Hülsenpaket".Both the sleeve rings 59 and the lever rings 61, the latter together with the Swivel
Dieser Aufbau bietet mehrere Vorteile: die Herstellung der Schwenkhebelringe 61 und der Hülsenringe 59 ist besonders einfach. Dabei führt die Herstellung der Au-ßenverzahnung durch Laserbearbeitung zu einem exakten Arbeitsergebnis und verursacht keine großen Kosten. Anstelle einer Laserbearbeitung kann auch eine Bearbeitung mittels Wasserstrahlschneiden eingesetzt werden. Bei dünnen Blechen empfiehlt sich auch ein Stanzen.This structure offers several advantages: the manufacture of the pivot lever rings 61 and the sleeve rings 59 is particularly simple. The production of the external toothing by laser processing leads to an exact work result and does not cause high costs. Instead of laser processing, processing by means of water jet cutting can also be used. Punching is also recommended for thin sheets.
Zudem ermöglicht diese konstruktive bevorzugte Ausführungsform einen modulartigen Aufbau der Kraftübertragung zwischen Schwenkhebel 45 und Hülse 49, wobei eine entsprechende Wahl zwischen der Dicke der plattenförmigen Hebel- bzw. Hülsenelemente einerseits und der Anzahl dieser Elemente andererseits zu einer äußerst flexiblen Ausgestaltung dieser Kraftübertragungselemente führt.In addition, this structural preferred embodiment enables a modular structure of the force transmission between
Alternativ können der Schwenkhebel und/oder die Schwenkhebelringe und/oder die Hülsenringe einstückig ausgebildet sein.Alternatively, the pivot lever and / or the pivot lever rings and / or the sleeve rings can be formed in one piece.
